Thanks to Luis, the hip-hop buyer at Amoeba Music San Francisco, for this week's top five, which includes in the number one slot the brand new triple CD release from Kool Keith, Lost Masters Collection.The record dropped on the Ultramagnetic hip-hop living legend's own Dmaft Records this past Tuesday. This 3 disc set (50 songs in total) is a must get for fans of the veteran, prolific, freaky-minded emcee. Also just released this past Tuesday is the full-length from popular Dallas native Dorrough, who previously scored a hit with the song "Do Tha Muscle" as a member of the group Prime Time Click. Simply titled Dorrough Musicon E1 Entertainment, the new album features the hot summer 2009 radio/club song and riding anthem "Ice Cream Paint Job" (see video below).
